Koronto, you will be welcomed bro...............
once you come to SD, dont worry about getting anywhere, because everything about somali is walking distance, pool table, somali-hang out spots, barbarshops, masjids, mukhaayets, supermarkets, and many other stuff, all these places are located in a place commonly known as somaliville, 92105, university avenue, I would also recomend you to chill out at the beach, private ( la jolla ) or public ( mission valley ), play soccer, football, picnic or what-ever, cus if your comming from cold places, it will be hot 70-80 degrees in May, some attraction are world famous San Diego Zoo located in balboa park and Sea Word, if you get a chance check those places out and mexico-is right around the corner--if you into getting stuff for cheap, hit those spots.
there's two masjid close to each other, around 50th street, one is called masjid nuur, owned by pakastanis since the 80's and the other one is called masjid al-ansar, owned by somalis who had enough of pakastani racism, any check both of them out since they very close to each other, there's many restraunts but I would reccomend, the one right next to minnihaha grocery store, also close to masjid al-ansar, more costumer friendly then the ogadeen one in 52th street,

, I also heard they just opened up one in 48th street, two blocks down!
kramer is right though, the highways or freeways are huge, I thought it was little till I seen the ones in minnisota and seattle, one more thing, gas is quite high up here during that time, so be prepared for that if your driving!
